Lifespan of a Bulb

For all Sperti sunlamps, the bulbs have a lifespan of 1,000 usage hours. This means that these bulbs can last your for years and years!

It is very important to keep track of how long and how often you use your sunlamp. After the bulbs have been used for 1,000 hours, there is a chemical change which causes them to become less effective. If you do not know how many hours your lamp has been used, there is not really an easy way to test the bulbs. You would need a special machine in order to sample the bulb’s UV output in order to see if it is still in a good, effective range. Since these machines are not easy to come by, the best way to test the effectiveness of your bulbs would be to simply use your sunlamp. After a couple weeks of use, you should be able to tell if you are getting the desired effects or not.

Once you are ready for new bulbs, you can order them directly from Sperti.com or by contacting our customer service office at: 800-544-3757
